The question is whether high-speed pursuits are actually necessary. Radio works at the speed of light, and before any high-speed chase the cops should think twice about the safety of civilians. Running at high speed through a school zone or a neighborhood with many children should be thunk twice before it's done. Yes, there might well be times when public safety supersedes the dangers to the public of such a chase -- an active shooter trying to escape, for instance -- but with the tools available to the police it might be easier just to pull a big truck across the path or use the aforementioned spike strips.

In truth, I know several cops and a high-speed chase scares the shit out of them. They know the dangers to themselves and others and except for the Adrenaline Few they'd prefer to avoid them (just as they would prefer not to shoot anyone). Out here in the Great Beyond the PD's cooperate well, so a baddy pursued onto, say, the Shoshone-Bannock Reservation (Ft. Hall) would be also pursued by the tribal police as well and the cops from the surrounding towns and the Idaho State Police...which does not mean it would be at break-neck speeds. More likely the tribal cops would spike the road.
